[PATCH v2 3/3] mem-pool: use consistent pool variable name

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

About half the function declarations in mem-pool.h used 'struct mem_pool
*pool', while the other half used 'struct mem_pool *mem_pool'.  Make the
code a bit more consistent by just using 'pool' in preference to
'mem_pool' everywhere.

No behavioral changes included; this is just a mechanical rename (though
a line or two was rewrapped as well).
